Webof Markov chains. In Section 3, we formally de ne our Markov chains and state the main results of the paper. Section 4 is devoted to the proofs of two of the main re-sults, and Section 5 is devoted to the proof of the third.

Before giving the general description of a Markov chain, let us study a few specific examples of simple Markov chains. One of the simplest is a "coin-flip" game. Suppose we have a coin which can be in one of two "states": heads (H) or tails (T). At each step, we flip the coin, producing a new state which is H or T with ...
